NAM is an abbreviation that stands for the North American region. It is used by international institutions and businesses when dividing the world into regions. Depending on the system they use, NAM can refer to all countries on the continent of North America or only the USA and Canada, sometimes including Mexico. For example, when a company uses the abbreviation LAC (which stands for Latin America and the Caribbean) then NAM refers to the USA and Canada since all other North American countries are already included in LAC.
